A test has been done using the same hardware configuration and now using RT-THREAD 4.1.1, but compiling two versions with some configuration changes:
a) First configuration:
**not using RT_USING_STIO
RT_USING TERMIOS**
The USB Host works properly:

b) using the same program but with
**RT_USING_STDIO
RT_USING_TERMIOS**
the device doesn't enumerate.
